Each creature in the affected area must succeed on a Constitution saving throw or take 4d4 poison damage and become poisoned for 1 minute. On a success creatures take half as much much and suffer no other consequences. At the end of a poisoned creatuers turn they reattempt the saving throw, ending the poison on a successful saving throw.
